鼻咽癌系我国常见恶性肿瘤之一。放射治疗是主要治疗手段,鼻咽癌原发灶一般采用多野体外照射,国内个别单位有配合应用腔内镭疗的资料,由于配镭和敷镭时工作人员易受辐射伤害,而且病员在敷镭过程中十分痛苦,未被广泛采用。我们从1980年3月起试用~(60)钴体外照射配合高剂量率~(60)钴遥控后装腔内照射治疗鼻咽癌原发灶,迄今已完成治疗85例,现将初步资料介绍如下: Nasopharyngeal carcinoma is one of the common malignant tumors in China. Radiation therapy is the main treatment method. The primary tumor of nasopharyngeal carcinoma is generally used with multiple field external irradiation. Some domestic units have data relating to the application of endovascular radium therapy. Since the staff with radium and radium are vulnerable to radiation damage, the patient is also The radium process is very painful and has not been widely adopted. We have applied ~(60) cobalt in vitro irradiation with a high dose rate of 60 cobalt to remotely treat primary nasopharyngeal carcinoma since March 1980. 85 cases have been treated so far. as follows:
